Santos joins Bellator following a four-year run on Brazil’s regional circuit. There, he’s posted an undefeated record, though his past nine wins have come via decision. The 24-year-old, who trains with Ze Mario Team in Brazil, is primarily a ground fighter with a stifling top game and developing striking skills.

Falcao, 30, went 1-0 in the UFC with a decision victory over Gerald Harris at UFC 123 but was released as the result of a nine-year-old assault charge in his home country of Brazil. Back to fighting, he enters Bellator on a 10-1 run that includes nine stoppages. In fact, in 28 career wins, he owns 26 stoppages (16 in the first round).

In a recent interview with MMAjunkie.com, he denied reports he had suffered a heart attack and said he was hospitalized simply due to overtraining and exhaustion.

In addition to the middleweight tournament, Bellator is hosting season-six tourneys in the bantamweight, featherweight, lightweight and welterweight divisions. Each tourney winner gets $100,000 in total pay and a guaranteed title shot.
